ABSTRACT:
Dual colorants are disclosed. The colorants of the present invention include at least one compound, which exhibits a first color outside an aqueous environment and a second color after placement into an aqueous environment. In some cases, the colorant includes an oil-soluble dye capable of exhibiting the first color and a water-soluble dye capable of exhibiting the second color. In certain embodiments, such colorants may be used in toilets. In these embodiments, the first color corresponds to a color associated with a fragrance, such as red for rose, while the second color corresponds to a color associated with cleanliness in a toilet, such as blue or green.
